Costello & Son Brush Co., St. Louis, Mo., a corporation of VMissouriAppunti@ July 1o, 1941, serial 1810.401363 2 claims; 01. 30o-2i) Thisinvention relates to certain new and useful improvements in a mop frameand pertains more particularly to theframes of that character of mopsknown to the trade as dustless sweeper mops for use of smooth-surfacedfloorings and whereby the swab structure of the mop is readily removableor replaceable and/or reversible if the swab structure is a double-facedone.

An object of the invention is toprovide a mop frame of an improved`construction.

Another object of the invention is'to provide an improved supportingframe for the 'swab structure and the handle of the mop, and Athe frameif desired, -`may be vprovided -with oiling ducts. l

A further object is tofprovide a mop frame with an improved handlesupporting head.

A still further object is to provide a mop frame of an improved tubularconstruction.

' 4It is also an object of the invention to construct a mopv frame by animproved method.

With the foregoing and other objects in view which. will appear as thedescription proceeds, myinvention resides in the combination andarrangement of parts and in the details of conbeing understood thatchanges may be made within the scope of what is claimed withoutdeparting from the spirit of the invention.

Anembodiment of the invention is illustrated in the accompanyingdrawing, wherein:

Figure 1 is a plan elevation partly in section of a mop showing thisimproved mop frame supporting the swab structure of the mop and thehandle. n

Figure 2 is a plan elevation showing how" this improved mop frame isconstructed.

Figure 3 is a perspective elevation of the mop frame head.

Figure 4 is an enlarged transverse sectional elevation takenapproximately on the line 4-4 of Fig. 2. v

Figure 5 is `an enlarged transverse sectional elevation takenapproximately on the line 5-5 of Fig. 1.

Figure 6 is an enlarged fragmentary longitudinal sectional elevationtaken on the line 6-8 of Fia-5.

Referring by numerals to the accompanying drawing, 1 designates the mop,8 the frame, and 9 the handle therefor.

The mop 1 as shown, comprises a doublefaced swab structure I0 of a pairof opposing secured together layers II having twine strands I2 securedto and extending outwardly from each layer, and the swab structure beingopen-.ended so that it can be slid from either end onto the supportingframe 8 before the handle 9 is fixed to the mop. l

f The frame 8 is of tubular structure and; is formed from a suitabletube length of relatively large diameter-and has rounded ends I3 whichare formed when making or constructingthe frame.` f' i 4In making theframe, a tube of the requiredV length for a frame of a desired size isselected, and the tubular length is marked as designated at I4 in Fig.-2 at the middle or center of its length, and an endI5 of the tube isengaged `and bent into a position paralleling the intermediate portionI6 ofthe tube on a required form of bend I'I, with the extending end I8of the pari-[I5 of the'tube intransverse alinementy with the mark I4.

A handle supporting head I9 having end disposed openings 20 and 2|respectively, and paralleling each other, is engaged for mounting on thepartly formed tubular length with the opening 2I engaged on'the straightportion 22 of the tubular length, and the head I9 is slid thereon to aposition so that the opening 20 of the head can' be engaged on the partI5 to the position shown in full lines in Fig. 2, and the head Iis leftin this position while the extending part of the straight portion 22 ofthe tubular length is being bent into a position in longitudinalalinement with the part I5 and wherein the extending endf23 will bepositioned in proximity to the extending end I8 of the part I5. Inbending the straight por-1 tion 22 of the tubular length into theposition shown at 22a in dotted lines in Fig. 2, the bend 24 is formed,the bends I1 and 24 thereby forming the rounded ends I3 respectively, ofthe frame 8.

The head I9 ateach end is provided with a pair of vertically disposedapertures 25 for alinelment with respective apertures v26 which areAformed in the tubular length when the head is moved to the positionshown in dotted lines at I9a, with the part 22a of the tubular lengthengaged in the opening 20 of the head. Pins 21 are then mounted andriveted in the alined aper tures 25 and 26 for securing the head t'o theframe. f

The head I9 on its top side 28 is provided with an inclined socket 29for the ferrule end 30 of the handle 9, and at the bottom of the socketis' an inclined seat -3I having a. slot 32 therein which is open at oneend for the reception of a threaded stud -33 which is secured to and exduct 31 which is drilled from the front end 38' of the head, through theopening 2| andthe well 34 and to the opening 29j-as iiire clearly shownin Figs. 4 and 5, before the'head-.is mounted on the frame 8.

In centrally disposing the head I9'1th fratrie 8 in the manner shown indotted-lines at IlSltin Fig. 2, the end 39 of the duct 31 will provide asite opening for locating the center mark l4- with respect to centrallypositioning the head on the frame for pinning the head to the frame.

V.Each of the layers l! of Athe swabvstructure l0 intermediate itslength, isprovided with asl-,it oropening 49 for introducing the ferruleend 30 'of the handle 9 for securing the handle to the head i9 of theVvframe 8 after the frazne has. been slid intothe swab structure fromeither end.V

The handle 9r` having the stud. 33 and tighten-A ing' nut 36Athreadingl'y mounted on. the .stud and held thereon against removal bythe burred end 4l on the stud, upon `being engaged Ain the slit lofther-upper layerv Il of the swab structure {D} is manipulated toguidingly engage the opposing sides ofthe nut between the opposed guidewalls. 39 inthe vhead l9so. that thatportion of the stud lbetween thenut and the' ferrule end of the handle can bedrawn into theslot 32. orthe seat" 3 and.. so thatthe ferrule Iendvl of the handle can be seatedinthe socket29 ofthe head.A Tighteni'ng turning of the handle 9 willcause the nut 36 to ride upwardly on the thread of the st'd 33 4leyreason of" the nut being held against turning by the opposed guide walls35, the'turn ing of' the Ihandle being continued until the Aferrule end3U thereof isrmly-seatedin the socket 29 of the head and against theseat 3|. Thermop is then 'ready for useon..smooth-surfacedgfloering'sand the like. l

Ohviousl-y, when one twine strand layer of vthe swab structur 'I hasheen suciently used, the

swab structure can beremoved from the frame 8 for reversing the workingsurface thereof, after removal of the handle from the head I9, which isdone by turning the handle in a loosening dlrection.

The tube -of the frame 8 may on its underside, be provided with spacedapertures 42 so that an oil treatment 'for' the swa'bstructurei In canbe provided by depositing olll in tlie'well- '34 from where it willenter the duct 31, and can be com- -x-nunicated to the apertures 42 'byentering the ytuhe through .the opening 43 at one end of theCbifiously'the securing of the head i9 to the Aextending ends of thetube-of the frame 8 prevents the tube ends from separating, and byreason of the frame being of tubular construction and the head beingsomewhat hollowed to providethe` handle securing vconstruct-ion shown; arelativelyA light weight mop frame is provided.
